Answer:
It determines how biological molecules recognize and respond to one another with specificity.
Explanation:
A molecule has a characteristic size and shape. The precise shape of a molecule is usually very important to its function in the living cell. Molecular shape is crucial in biology because it determines how biological molecules recognize and respond to one another with specificity.
The downward pressure on the hg in barometer is <u>the same as</u> the pressure of the atmosphere.
The atmospheric pressure or barometric pressure is the force exerted by the air in the atmosphere on the earth's surface.
The atmospheric pressure is caused by air molecules colliding with the surface. The atmospheric pressure at sea level is about 101 kPa and at the cruising altitude of a passenger plane it is 27 kPa.
The atmospheric pressure decrease as the height of a surface above ground level increases.
<h3>What is a barometer?</h3>
A barometer is a measuring instrument used to measure the atmospheric pressure or weight of the air, which is useful for making weather predictions.

Explanation:
The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.
